Don Norman concludes "The Design of Everyday Things" with a call to action for all designers and users:
I appreciate the consistent voice Norman helps give to the user, to know that you are not at fault for not being able to work with a poorly designed product, and that good design can do something far more grand that just created easy-to-use products: it could change the world. I share in Norman's dream to see the "rise of the small" - to see individuals come together from all fields of study to continue to develop interconnectedness on a global scale: giving rise to open-source software that anyone can adapt for their open purposes, open-source 3D printers, and open-source education that can help expand access to education in areas where even basic literacy is limited.
These seemingly small tools are efficient, and with good design, can be used by anymore, allowing the user to make huge gains in areas where they were previously limited by lack of availability or bad design.
